mafiozo [28]

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.

The ratio of estrogen to progesterone remains constant throughout pregnancy into labor. false/true
Lady_Fox [76]

False,

In order to start labor, estrogen increases and progesterone decreases.

Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.

Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.

At the start of a 100-yard dash (race), your body relies on which reserve as its energy source?.
Rama09 [41]

The human body reserves creatinine phosphate as the energy source at the start of 100 yard dash (race).

The creatinine phosphate is converted into ATP, which is the energy package of our body. ATP is body's usable form of energy. Energy is stored in various forms in our body such as fats, carbohydrates and proteins. At a microscopic level, it is stored in molecules like creatinine phosphate. Carbohydrate and fats are the primary source of our body followed by proteins.

Our body uses three different forms of metabolism to convert these molecules in ATPs. These three processes are Phosphagen System, Aerobic Respiration and Glycolic/Anaerobic respiration.

The ____________ is sometimes called the "funny bone" because of the tingling sensation (pain) one feels if the ____________ is
Alex

Answer:

<u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.

Explanation:

The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus),  ulnar nerve is called funny bone.

The nerve is relatively unprotected at this place.

A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.

Hence, <u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
